The properties of solutions of linear differential equations with entire coefficients of finite iterated order

In this paper,we investigate growth problems of solutions of a type of homogeneous and non-homogeneous higher order linear differential equations with entire coefficients of iterated order.

In this paper,we study the finite iterated order of growth and the iterated convergence exponent of the zero sequence of nonzero meromorphic solutions of second order homogeneous linear differential equation,and obtain some precision evaluation.

And an incremental iterative algorit.

Considering the influence of edge effect,the static-electricity driven torque was amended,the nonlinear mechanical model of a torsion micromirror was established and the static mechanical equation of micromirror was solved by an incremental iterative algorithm.

In order to guarantee the convergence and stability in solving nonlinear algebraic equations, an incremental iterative algorithm was put forward according to the load characteristic.

The traditional multiple exchange algorithm is modified to obtain part coefficients with floating point precision when the other are fixed,and the resulted algorithm is combined with an iterative quantization procedure in which all the coefficients are quantized one by one.
